Lesson: 1.08Given this function: f(x) = 4 cos(TTX) + 1Find the following and be sure to show work for period, maximum, and minim

Ber [7]

The given function is

$f(x)=4\cos \text{(}\pi x)+1$

The general form of the cosine function is

$y=a\cos (bx+c)+d$

a is the amplitude

2pi/b is the period

c is the phase shift

d is the vertical shift

By comparing the two functions

a = 4

b = pi

c = 0

d = 1

Then its period is

$\begin{gathered} \text{Period}=\frac{2\pi}{\pi} \\ \text{Period}=2 \end{gathered}$

The equation of the midline is

$y_{ml}=\frac{y_{\max }+y_{\min }}{2}$

Since the maximum is at the greatest value of cos, which is 1, then

$\begin{gathered} y_{\max }=4(1)+1 \\ y_{\max }=5 \end{gathered}$

Since the minimum is at the smallest value of cos, which is -1, then

$\begin{gathered} y_{\min }=4(-1)+1 \\ y_{\min }=-4+1 \\ y_{\min }=-3 \end{gathered}$

Then substitute them in the equation of the midline

$\begin{gathered} y_{ml}=\frac{5+(-3)}{2} \\ y_{ml}=\frac{2}{2} \\ y_{ml}=1 \end{gathered}$

The answers are:

Period = 2

Equation of the midline is y = 1

Maximum = 5

Minimum = -3

Answer:

A = 110 degrees.

Step-by-step explanation:

< A and < B are same side angles so their values add up to 180 degrees, so:

5x + 20 + 9x - 92 = 180

14x - 72 = 180

14x = 252

x = 18.

So m A = 5(18) + 20

= 110 DEGREES.

A college student would like to investigate the prices of sandwiches offered near the campus. A sample of 50 shops that sell san

elena-14-01-66 [18.8K]

The interval from $9 to $10 contains the largest number of sandwich prices. Option B

<h3>Which is a correct statement regarding sandwich prices, based on the histogram?</h3>

Generally, A graph known as a histogram displays the frequency of occurrence of numerical data via the use of rectangles. The frequency of a variable's distribution is shown by its position along the vertical axis, which is the height of a rectangle (the amount, or how often that variable appears).

In conclusion, The greatest number of sandwich costs may be found in the range from $9 to $10. Alternative B
